I got a problem with streaming YouTube videos. After around 30sec to a minute of watching the video gets cut off and the progress bar starts "loading" indefinitely. It's possible to quit the video and restart it to watch a bit more until it stops again.

Has anyone had this problem? Interestingly it seems to be a YouTube problem only. Sites like Vimeo and Youku (Chinese YouTube) don't have this problem.

I'm using the standard browser/YouTube app.
